CARPET-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 235,085, dated December7, 1880.

Application filed May 3, 1879.

To all whom it may concern Be it known that 1, JOSEPH Hnssn, of SanFrancisco, county of San Francisco, in the State of California, havemade and invented certain new and useful Improvements in Carpet-SewingMachines, which invention is fully set forth and described in thefollowing specification and the accompanying drawings, making partthereof.

My invention relates to certain improvementsin sewin g-machinesspeciallyconstructed and adapted for sewing together the breadths ofcarpets, the carpet being suspended in a fixed position, while themachine rests astride of and travels upon the edges; and the inventionconsists in the construction and arrangement of the various devicesforming parts of the machine, as hereinafter more fully described andclaimed.

In the accompanying drawings, Figure 1 is a side elevation of myimproved machine. Fi 2 is a front elevation of the same. Fig. 3 is ahorizontal section through a; :r, Fig. 2, showing the feed mechanism formoving the machine intermittently forward over the carpet. Fig. I is anenlarged detail view of the upper part of the saddle-frame, the springpresserplate, and the supporting standard or bracket. This view is takenfrom the right-hand side of Fi 2. Fig. 5 is an enlarged side view of theplate having the turning guides. Fig. 6 is an enlarged detail view ofthe vibrating looper and its mechanism, by which both the vibratory andthe rising and falling movements are given. Fig. 7 is a central verticalsection of Fi 1, showing the needle-bar in connection with its operativemechanism; and Fig. 8 is a detail view, showing the position andarrangement of the plate-spring.

In this machine the saddle-plate A is made with its front limb, A, ofmuch greater length than the rear one, and with a bearing or stud, b,for the balance-wheel B near its lower end, and as low down as possiblebeneath the point of suspension of the frame, where it rests astride ofthe carpet. This construction affords greater extent of surface of thefront limb to bear against the vertical side of the carpet, and thuskeeps the saddle-frame in a proper upright position as it moves along,and it also insures a steady movement and operation of the machine bybringing the weight of the balancewheel much lower down beneath thepoint of suspension of the frame.

The spring presser-plate O, which is placed within the space embracedbetween the two limbs of the saddle-frame, is adjustable, by means ofthe set-screw 0, toward and away from the inside of the opposite limb,so that the two thicknesses of carpet are compressed with the requiredpressure between these two surfaces.

The upper edge of the plate (J has an angular bearing-surface, d, at anangle of fortyfive degrees, or thereabout, and the opposite corner inthe bend of the saddle-frame is filled in or provided with a similarangular surface, (1. Between these two surfaces the edges of the carpetare introduced when the machine is placed in position and as the topedges bear and run against these inclined gage-surfaces, and one of thesurfaces, d,is ad justable,it will be seen and readily understood, fromexamination of Fi 4, that when these two angular faces are broughtcloser together the carpet edges inserted between them cannot approachso near to the horizontal plane in which the needle reciprocates, andtherefore in such adjustment the line of the stitches will be madenearer to the edge of the carpet. The reverse will take place when thetwo angular surfaces are adjusted farther apart. By this means the twoedges of the carpet, whatever their thickness, are smoothly pressedtogether-immediately about the needle, and the distance of the seambelow the edge is at the same time readily regulated.

The needle 0 is a curved eye-pointed one, and is reciprocated in acurvedhorizontal path through suitable needle holes or slots in the sides ofthe saddle-frame.

The needle-bar E is curved, and moves in a curved groove or slots in thefixed standard D, that is secured by its curved arm D to thesaddle-frame. Its reciprocation is produced from the upright shaft F bythe crank f and the curved connecting-rod G, attached by balland-socketjoints 9 g to the crank and to the upright at the rear end of theneedle-bar or slide E.

By this construction and arrangement of devices the movements of theneedle are effected in a horizontal direction in a positive manner andwith greatly increased power.

The means for producing the required intermittent vibrations of thelooper h are more particularly shown and described in the Letters PatentNo. 195,277, issued to me on the 18th day of September, A. D. 1877; butin connection therewith I employ a novel means for giving the requiredvertical or rising and falling movements to the looper h at the end. ofits forward and the beginning of its backward movement, which are shownin the view Fig. 6.

The looper-shaft H has a projecting pin,j, which engages with a slot,70, in the reciprocating slide or needle-bar E, and the shape of thisslot is such that as the slide moves back and forth the rock-shaft Hwill be raised and dropped at the proper times.

Above thelooper and the needle, and in line with the latter, I place afixed rod, J, with aflattened beak. This rod is held directly over thepath of the needle and at a sufficient distance above the point of thelooper to allow the needle to pass freely between the two, and thisconstitutes a means for keeping the point of the needle always in adirect path and preventing its being accidentally sprung or raised toofar above the hook of the looper, by which no interlooping of thethreads could takeplace. This rod J passes through a socket in thebracket D, where it is held by a clampingscrew.

Upon the top of the saddle-frame, and in a slot therein, is placed aguiding lip or blade, Z, with a beveled or inclined under surface. whichI provide for the purpose of turning in, out of the way of the needle,any raveled or frayed edges of the right side of the carpet that may beproduced in the cutting; and in connection with this blade I alsoconstruct a turning beak or horn, on, which projects from the front endof the saddle-frame a short distance to act upon the carpet before theedges reach the needle. This horn rests between and separates the twoedges of the breadths or pieces of carpet to be sewed, and as themachine moves forward this part m passes between the two edges and turnsupward and outward any folds or portions that may have curled inward andtogether as the carpet hangs suspended. These two parts Zm are securedto or are formed with a plate, K, Figs. 2, 5,which is held on the frameby a screw, 01..

The means for moving the saddle'frame forward over the carpetedges tospace the stitches consist of an intermittent four-motion feed on thefront side of the plate or limb A of the frame. The points of thefeed-bar project and work through a slot or opening in the frame and inthe pressure-plate, and engage with one side of the carpet.

The feed-bar L is moved forward by the action of the cam 0 upon therotating shaft F, and backward by the plate-spring S, attached to theframe. It reoiprocates upon the stud 10, held by the bracket q, fixed tothe frame, and its outward movement away from the carpet is effected bythe spring 1. This construction is illustrated in Figs. 3 and S.

The reciprocating slide or needle-bar E carries suitable thread-guidesand a spool-spindle, and the frame below is provided also with spindleand guides for the looper-thread.

As thus constructed myimproved machine performs the work required of itin a rapid and uniform manner. It maintains an upright or perpendicularposition with the carpet, and but little effort on the part of theoperator is required to guide it and operate the drivingwheel.

Having thus fully described my intention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination, with the saddle-frame A A, of the fixed angulargage-piece d within the bend of the frame, and the spring pressure-plate(3, provided with a like gage-piece, d, and means for adjusting saidpressure-plate toward and away from the said fixed piece, substantiallyas and for the purpose set forth.

2. The plate K, formed or provided with the beak or horn m and thebeveled blade I, in combination with the saddle-frameA A, substantiallyas and for the purpose specified.

3. In acarpet-sewing machine, the combination of the saddle-frame A A,curved eyepointed needle 0, and mechanism for moving it in a curved pathand horizontal direction, curved needle-bar E, having cam-slot Ir,curved guide-standard D, loopershaft H, having stud j, looper h, andmechanism for imparting a rotary horizon tall y-reciprocatin g motionthereto, stationary rod or bar J, and bracket D, all constructed andarranged to operate as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this22d day of April, 1879.

JOSEPH HESSE.
